[68.07] Neutrinos from Blazars and the Differences between FRI and FRII Radio Galaxies

Nonthermal proton acceleration in galaxy jets produce
neutrinos through photomeson production. Sources with
intense surrounding fields should be strong neutrino
sources. Neutrons and high-energy photons formed through
photomeson processes will transport inner jet energy far
from the black hole engine to power distant jets, hot spots
and lobes, as observed at X-ray energies with Chandra. This
effect may account for differences between the FRI and FRII
classes of radio galaxies that display distinct
morphologies.
